Building a strong professional network, investing in ongoing training, and utilizing specialized project management tools can help address these challenges and maintain high-quality service.

What is freelance protection relay testing?

Freelance protection relay testing involves independently assessing and verifying the functionality of protection relays in electrical power systems. These relays are critical for detecting faults and safeguarding equipment by triggering circuit breakers during abnormal conditions. Freelance testers are not tied to a single employer and are often contracted by utilities, industrial plants, or engineering firms to ensure relays are correctly installed, configured, and performing to standards. The role typically requires technical expertise, specialized testing equipment, and knowledge of industry standards such as IEC or IEEE.

What are the key skills and qualifications needed to thrive as a freelance protection relay testing engineer, and why are they important?

To thrive as a Freelance Protection Relay Testing Engineer, you need a strong background in electrical engineering, in-depth knowledge of protection schemes, and hands-on experience with relay testing, typically supported by a relevant degree or certification. Familiarity with specialized relay testing equipment (such as Omicron, Doble, or Megger), report generation software, and industry standards like IEC or IEEE is crucial. Attention to detail, strong analytical thinking, and effective communication are standout soft skills for collaborating with clients and resolving complex technical issues. These skills ensure accurate system protection, compliance with safety standards, and client satisfaction in critical power system environments.

Job description

Description
This position will offer you the ability to directly apply your knowledge of protective relaying and controls systems for HV and EHV substations. As a Lead Substation Engineer, you will:
  • Work on a wide range of substation modifications and upgrades to support client requirements and reviews including creating calculations, document designs, and specifications.
  • Prepare relaying philosophies, including selecting relay, control, and communications equipment, developing SCADA and telecommunication concepts and configurations, and overseeing the preparation of I/O assignments and connection diagrams.
  • Guide junior and senior-level engineers and designers in protection and controls engineering design efforts, including providing guidance with the coordination of detailed design phases for all aspects of the engineering work.
  • Support challenging assignments that include investigating, trouble-shooting, and solving a wide variety of engineering issues.
  • Perform analysis and design of single line diagrams, substation relaying & metering diagrams (i.e. A.C. schematic diagrams), and D.C. Schematic diagrams.
  • Prepare engineering studies for client and peer review.
  • Perform independent reviews of work performed by others including calculations and drawing preparation.
  • Coordinate and provide guidance to other engineers, project managers, client personnel, and suppliers to ensure a complete and timely design.
  • Perform reviews of existing facilities to propose upgrades and replacements, and present findings and recommendations to clients and peers.
  • Develop your career via peer-learning through sharing of knowledge with other experienced engineers by way of Sargent & Lundy's systems of process and associated "Communities of Practice."
  • Provide guidance as a mentor in the development of less experienced engineers.
  • There is the potential for you to travel to client and vendor offices for design reviews and to plant site locations for construction coordination and field verification of designs.

This role offers a hybrid work arrangement, with the expectation of spending three days a week in the office, giving you the flexibility to work remotely for two days.
Dependent upon your location, this opportunity offers a generous relocation package.
